ultimately i think what they both need is understanding? in the sense that- both have very specific experiences in their day-to-day lives that aren't exactly the common shared experience between most other people. zhongli is a fucking eons-long being and alhaitham is not neurotypical. like he's autistic, idk how else we want to put it, that's what he is. zhongli, meanwhile, by virtue of not being a human and not having a strictly human way of processing the world, cannot be autistic since- again, not human. but this does make him autistic-coded, if that makes any sense. my man despises slimy foods on the basis of the texture (yes, this comes from trauma, but what bothers him is still the texture. that's coding). he's not human so he has different sensory experiences, probably more acute than humans. he's been described as a blockhead. he seems like he'd have a very specific routine he follows. he's very exacting on his field of expertise. the whole 'haha no mora no wallet' situation comes from the fact that his brain is still logically thinking he can just make mora (which, given everything, is a perfectly valid thing to still be hung up on), and so he forgets his money because his mind insists the way of the world is that he can just make it - but he can't anymore, and for an arbitrary reason, too. he's the literal god of contracts: what are contracts if not a parameter of very logical pre-established rules you have to follow? and he doesn't bend on those contracts, because he's of the mindset that if you made them in the first place, you knew what you were getting into, so what's the problem. all combined, and added with the fact that he's not human, and you cannot call him neurotypical. because he just does not function to match human standards of what 'neurotypical' even is.

so like- we don't know that they've met in canon, but we have decent reason to believe it's a very real possibility. the same way you could say gaming and ganyu have probably either met or seen each other at least once despite neither ever mentioning the other or appearing together on screen, because- well, he handles a delivery agency, she works for the qixing, they live in the same city, they're both familiar with cloud retainer, ganyu moves around a lot and knows a lot of people, and gaming seems pretty social. you get what i mean, right? in that same sense, i think it's perfectly possible for alhaitham and zhongli to have met at some point. granted nowhere near as probable as two people actually living in the same city, but notable enough nonetheless: alhaitham knows twenty languages, for that quota to exist i have to assume that each nation has at least their own unique language (since they all seem to speak the same thing in-game, tho, i can only translate that as all nations having their unique writing script- which they do). idk how many languages you could pull out of regional dialects in teyvat, but the most logical and easiest and obvious thing to do here if you were told to go learn 20 languages to graduate is to first go for the main most spoken languages and then fill in the gaps w regional dialects or more obscure no-longer-spoken ancient dialects. so we stand to reason alhaitham must know liyuean (?) right? and unless he learned it from within the confines of sumeru (which is possible tbf), then he must've traveled to liyue in order to learn the damn language. with liyue having quite the decently-preserved history, he might've picked other regional dialects up since they'd be easier to study next to like- idk, an obscure old language from mondstadt or smth. so if you're a student in liyue on a quest for knowledge trying to learn the language and possibly other obscure dialects, who are you going to go after? fellow scholars. what do all fucking scholars in liyue do when people have highly-specific needs and questions? point to fucking zhongli. so you get where the idea comes from. you can't tell me its completely implausible (for a headcanon) for zhongli and alhaitham to have met at some point, not the same way i'd raise eyebrows at like- headcanoning candace and zhongli having met based solely on in-game info. or- ei and sigewinne. y'know?

so like- alhaitham needs to learn liyuean (+ maybe other regional dialects bc 20 sounds like quite a lot for 7 nations, 8 if you count khaenri'ah), he goes to liyue, he gets to learning and then runs into the roadblock of not many scholars being familiar enough with ancient dialects for him to become fluent in them from their input alone, so the scholars are like 'yeah dw we know a guy, he's super knowledgable' and so they point him to zhongli, zhongli is like 'yea sure i can teach you, what do you need?'. idk how long it'd take alhaitham to learn liyuean (+ whatever else), but i'd assume he'd bunker down in liyue for most of that time. so let's say like- 6 months, and it counts as like a 'foreign languages' course where haravatat students get given money and are shipped off to learn (bear in mind 6 months sounds like stupid little to become fluent in an entire language let alone possibly a few others, but we'll just assume alhaitham is a prodigy (he seems to be) + since it's not a whole language and just a script, then it can be done).

so he stays in liyue for a while. i'd guess learning from zhongli most of that while. they're two guys who like peace and quiet and reading and investigating and they're both rather knowledgable (the gap is obviously abyssmal but still). you can imagine them just- going to a tea house and sitting down with tea for hours on end in amiable silence and quiet grammar exercises. i cannot see them not getting along. alhaitham is practical and so is zhongli, zhongli has a lot to say but it's always with purpose and informative and for a reason, and alhaitham is just happy to absorb knowledge. alhaitham is effective and to the point and zhongli (a battle general) would probably be perfectly happy rolling with it and being effective and to the point in turn. maybe they start having lunch together some days (zhongli does seem to do that with acquaintances a lot so it's not strange of him) and alhaitham just doesn't want any stewy soups and zhongli doesn't question it bc he's the one asking chef mao to dice and slice his fish into oblivion. sumeru is big on spices so alhaitham would probably have no problems whatsoever w the jueyun chilli. he'd also probably pick up on using chopsticks easily enough bc he's a perfectionist. zhongli would realise like two seconds into their introductions that alhaitham can hear him perfectly loud and clear w the headgear on and never bother commenting on it at all. alhaitham would also probably clock zhongli's more acute senses two seconds in and be relieved he doesn't have to raise his voice around people for no reason all the time. catch the patrons at the tea houses being confused and mildly unsettled by the two guys on the corner table just mumbling stuff to the other with a pile of books between them lmao

i cannot see their relationship being like- exciting in the sense that big shocking things happen. i just think they're both too smart and good at communicating w each other that shit like that just wouldn't catch them off guard. alhaitham would probably hear about legends of the adepti throughout his stay in liyue and quietly figure mr zhongli might be an adeptus but never bother saying anything because why should he care about what mr zhongli is? it's not his business, and it doesn't make him not-mr zhongli. so it's whatever. i also don't think any drama would pop up 🤷‍♂️ again they're too smart and hypercompetent for any misunderstandings to appear. by virtue of both of them being non-neurotypical they'd also understand each other in particular ways, so they'd easily be able to figure out any stuff and sand off any rough edges. it wouldn't be an exciting ship, it wouldn't be a ship full of ups and downs and drama and twists and turns and spice and oh the romance of it all. they both strike me as ace af and if not aro then absolutely somewhere in the spectrum, alhaitham more than zhongli.

but i'm an absolute sucker for non-verbal comunication and quiet understanding and an almost telepathic camraderie that would be so funny from the outside so i just think they'd be a delight. like the perfect team. they get each other, they're both smart, they're both strong (again, the gap is abyssmal). absolute academic weapons the both of them. catch someone being an ass about a contract and zhongli just staring disappointed and alhaitham next to him equally disappointed but listing off every single reason why they're being stupid about it also. zhongli's a bit too nice to say any of that stuff aloud but you can't tell me he wasn't running a constant 'chat are you seeing this shit?' in his head during his first story quest w kliment. alhaitham knows he's already got the 'freak' reputation so he just goes 'well if you want to keep digging i'm happy to hand you a shovel'.

as for other characters' reactions to them- i'd have to sit and think about them? idk how the liyue gang would react bc idk how they'd work in a canon setting? i can't see zhongli leaving liyue and i can't see alhaitham leaving sumeru either. if i had to pick one, alhaitham seems more likely for like- leave sumeru for plot reasons. and then go 'okay fuck this' and go to zhongli like 'you're the only bitch i respect in this house'. but outside of plot contrivances, hu tao does send zhongli off on random errands? so maybe he could pop up in sumeru from time to time. idk how the liyue gang would get to meet alhaitham then but if there is one character that absolutely gets to meet zhongli is kaveh bc the man is almost everywhere alhaitham is + they literally live together.
